We have used the first form in all places that are performance sensitive.
The second form is sometimes used in very infrequently-used methods.

We are aware of the impact of synchronization. As a result David Nordahl has
developed our implementations of List objects which do not use
synchronization. Please download the 1.7.2 ALPHA B source package from the
